Evaluation of the layout of old community public facilities from the perspective of healthy community:Taking Wangfeng Community in Wuhan as an example
From the perspective of a healthy community,equitable distribution of health facilities is crucial for ensuring fairness in residents'health outcomes.The rapid urban development and conflicting needs between outdated community infrastructure and the demands of contemporary residents highlight pressing issues.Current academic discourse and regulatory standards primarily focus on macro-level controls and guidance,leaving significant exploration space on how to effectively apply concepts like healthy cities or healthy communities in practical assessments.Additionally,there is a lack of comprehensive measures at the community scale to finely assess the layout of facilities in older neighborhoods.In the context of healthy communities,there remains no established consensus on the guiding principles and methods to optimize the layout of health facilities,especially in older residential areas facing greater challenges compared to newly planned ones.Reasonable facility planning is one of the essential components in constructing a healthy community,and discussions on health facilities cannot be divorced from this planning.This paper first identifies which types of facilities fall within the scope of discussion.Health inequality is defined as systematic differences in health status among different social groups,emphasizing the connection between facility equity and resident health.The construction of a healthy community is inseparable from a healthy medical service system,and medical and health facilities are important parts of urban public service facilities.In the context of aging,good community service facilities for the elderly are necessary to support the urban pension system and build a healthy pension model.Community environmental sanitation service facilities are an important foundation to ensure comfort and convenience and are conducive to creating a clean and hygienic community environment.In addition to community medical facilities,health facilities,and social welfare facilities that ensure resident health,health facilities also include other facilities that promote the physical and mental health of community residents,such as cultural and sports facilities,and educational service facilities.Educational service facilities such as primary and secondary schools,kindergartens,etc.are important facilities to promote the healthy physical and mental development of students and young children.Promoting national fitness is one of the important components of realizing healthy cities and healthy communities,so a more equitable layout of cultural and sports facilities is of great significance for building healthy communities.The rational planning of these facilities has a direct impact on residents'quality of life.The purpose of this study is to explore an evaluation system for public facility layout in aging communities from the perspective of a healthy community and to discuss pathways for improving facility layout.Firstly,this paper selects the Wangfeng Community in Wuhan as the scope of empirical research.This area is one of the key regions for local government renovation of aging neighborhoods.The residents in this area are primarily middle-aged and elderly,closely connected to healthcare facilities in their daily lives,with a high demand for walkable accessibility to facilities among the elderly.Public facility Points of Interest(POI),facility scales,and population data are collected and filtered using API interfaces to construct a vector dataset of map elements.Based on the"Community Life Circle Planning Technical Guidelines"as a standard,thresholds for various types of facilities are selected and specified.An improved two-step floating catchment area(2SFCA)method is employed to analyze the accessibility of existing public service facilities.Subsequently,the matching between community population distribution and the capacity of each facility to serve the population is calculated to further evaluate facility supply capabilities.The evaluation results indicate inadequate accessibility and imbalanced supply of facilities in the studied area.In contrast to new residential areas,the renovation of facilities in older neighborhoods emphasizes the macro-level control of existing space and resources to enhance public facility distribution for a more rational layout.Subsequently,based on evaluation results,an optimization pathway termed"classification of functional differences-exploration of latent spaces-embedding of applicability"is proposed.Firstly,for facilities with different functions,the space use area varies due to the different needs of their users and relevant regulations.Therefore,the differences in the space requirements of different types of facilities can be clarified through the classification of facility functions.Secondly,due to the early planning of old communities,there is usually limited space for new construction.It is necessary to fully tap the potential space and realize space activation through renewal,sharing,and supplementation.Thirdly,on the basis of clarifying the above two points,the facilities should be allocated according to local conditions based on the differences in demand and disposable space.Following this,a secondary evaluation of the reorganized facilities shows that the optimization strategies significantly enhance accessibility and service supply in the community.An attempt to investigate the relationship between traditional settlements and rising concepts is made through the study of old neighborhoods.This study presents a comprehensive evaluation of accessibility and supply capacity from the standpoint of healthy community,and it quantifies the accessibility of health services and the population that can be covered.In addition to offering helpful ideas for developing a more wholesome pattern of urban community amenities and sustainable urban development,the research framework of this paper offers some support for the public service facility evaluation system in older residential districts.
